Critical vs critical block?

So Is it possible to get a critical hit on someone with a 100 percent block rating? And if so, how do you do it(Is there a spell that can help or some gear or something)? I know that someone who is level 80-85 and up typically have a 100 percent block rating or close to it, so what is the point of critical ratings at that level if you can't critical hit them anyway?

Any help is greatly appreciated.

Actually, most people no matter the level don't have 100% Block. 100 Block Rating is not the same as 100% Block. 100 Block Rating at level 50 would be about 27%, 26% at level 60 and so on. And that's assuming you get all of it from one piece of gear. These Duelist101 guides will help you understand critical better:
